    This paper presents a design and implementation of biquad digital filter based on poles-zeros placement on a unit circle of z-plane. The proposed digital filter can be given three frequency-responses as lowpass filter (LPF), highpass filter (HPF) and bandpass filter (BPF) at the same time. In the design process the Matlab program was used, for real world implementation by using TMS320C31 DSP board. The experimental results shown by the dynamic signal analyzer to indicate that the obtained frequency responses give the same results as design specifications.

    The following paper presents the design and implementation of IIR notch filter with modified pole-zero placement algorithm. The proposed modified algorithm is derived from the least square estimation to change the pole position and find the estimated values of coefficients to control the new gain level of the pass-band. The results from the algorithm are shown, the algorithm could control the pass-band gain of the notch filter according to the specifications. The result has been simulated by using MATLAB.
